Bobbin holder adapter

Abstract

A bobbin holder adapter facilitates replacing bobbins in a yarn feeding system called a creel, and which is formed by bearing of a constant lower table and a movable upper table on a central shaft. Further, a motion restriction component is positioned on the upper table for restricting the motion of the upper table around the central shaft bearing the upper table and for stopping the adapter at the desired point, a motion restriction housing is formed on the lower table for enabling movement of the motion restriction component, a locking ball is provided for keeping the adapter in the optimum position for unreeling yarn, a locking spring is positioned on the upper table for applying force on the locking ball, and a locking housing is formed on the lower table, on which the locking ball makes pressure as a result of the force applied by the locking spring.

DETAILED DESCRIPTION OF THE INVENTION

(11) In this detailed description, the bobbin holder adapter (100) which facilitates replacing bobbins (M) in a yarn feeding system called creel (C) is only disclosed for better understanding of the subject.

(12) FIG. 1 gives a representative view of the bobbin holder adapter (100) according to the invention on a creel (C). The connection of the bobbin holder adapter (100) on the creel (C) is made by means of a mounting surface (1), to which one of the main components of the bobbin holder adapter (100), a lower table (10) is attached via a fixing nut (35).

(13) FIG. 2 shows the general perspective view of the bobbin holder adapter (100), while FIGS. 5, 6, and 7 shows the perspective view from different angles. Accordingly, the bobbin holder adapter (100) is formed by means of bearing of the lower table (10) forming the main structure and stable part of the system and the upper table (20) forming the movable part of the system on a central shaft (30).

(14) The lower table (10) is fixed to the central shaft (30) via a lower table fixing screw (13). The upper table (20) is connected to the central shaft (30) via a fixing washer (40) and a fixing screw (45).

(15) The bobbin (M) is attached to the bearer shaft (2) that is connected to the bobbin holder adapter (100) via a bearer shaft fixing nut (5), and the bearer shaft (2) is fixed by means of a clamping spring (3). The clamping spring (3) is connected to a mounting component (4) and the same mounting component (4) is connected to the bearer shaft (2).

(16) When a full bobbin (M) is attached to the bobbin holder adapter (100) and brought to operating position or retracted to replace an empty bobbin (M), the upper table (20) makes a free rotational motion around the central shaft (30) bearing the upper table. In order to restrict this motion of the upper table (20) and stop the adapter at the desired point, a motion restriction component (12) positioned on the upper table (20) is moved within the motion restriction housing (11) opened on the lower table (10). FIG. 8 shows a representative top view of the movement of the bobbin holder adapter (100) in A and B directions. The angular movements of the upper table (20) in A and B directions is stopped by means of the motion restriction component (12) leaning against the end points of the motion restriction housing (11). In this way, further movement of the bobbin holder adapter (100) in each direction is restricted and the movement in both directions are taken under control.

(17) FIG. 3 shows the detailed view of the parts forming the bobbin holder adapter (100), and FIG. 4 shows the mounted/demounted view of these parts. In order to keep the bobbin holder adapter (100) in the optimum position for unreeling yarn, an adapter locking system formed of a locking ball (22) and a locking spring (23) is used. Said locking system is actuated by the locking ball (22) entering into the locking ball housing (21) found on the lower table (10). When a full bobbin (M) is attached and the bobbin holder adapter (100) is moved towards direction B, the upper table (20) starts to rotate around the central shaft (30) and when the locking ball (22) corresponds to the locking ball housing (21), the locking spring (23) pushes the locking ball (22) into the locking housing (21). In this way, the bobbin holder adapter (100) is locked at this point and enables holding the bobbin (M) at an optimum position for unreeling yarn. The locking spring (23) is kept constant in a housing found on the upper table (20) via a spring pressure adjustment screw (24). The function of the spring pressure adjustment screw (24) is to make the force applied by the locking spring (23) onto the locking ball (22) during the locking operation adjustable. Besides, the pressure of the locking spring (23) can be increased or decreased according to the weight of the bobbin (M) worked with.

(18) When the bobbin holder adapter (100) is retracted in direction A for the purpose of replacing an empty bobbin (M), the locking ball (22) pushes the locking spring (23) in the opposite direction and thus it is freed from the locking housing (21). During this movement, the motion restriction component (12) found in the motion restriction housing (11) starts moving in direction A and after reaching the end point, it stops the motion of the bobbin holder adapter (100).

(19) With the present invention, replacement of bobbins (M) is made easier with the rotating structure of the invention, and the amount of force required for rotating the bobbin holder adapter (100) is also reduced with the lock mechanism found in its structure. In this way, operating performance is improved by means of enabling a worker to perform the operation with one hand. Moreover, abrasion is also prevented, since the locking ball (22) would make a rolling motion on the lower table (10).
